Description
Technical Field
The present invention relates to the technical field of machines for painting (painting, coating) panels of various materials (wood, glass, asbestos cement, plastics, etc.). In particular, the present invention relates to a front extractable cart for cleaning the transport system of workpieces and for recovering paint, provided with at least a solvent storage and recirculation container for storing and recirculating the solvent separated from said cart, placed on the side of a spraying apparatus.
Background
It is known in the art that not all of the coating ends up on the workpiece to be painted during painting; a small portion of the coating undesirably ends up on a conveyor, typically an enclosed belt conveyor, that transports the workpiece to be painted. For example, EP1964794a2, EP3165480a1 and EP1964795a1 of the same applicant describe various arrangements of scrapers and hoppers or tanks and/or other devices for scraping and wetting the lower return section of an enclosed belt conveyor to remove the paint which has made it dirty during spraying. Typically, the coating is mechanically removed and the conveyor return section is then wetted with solvent for finer cleaning. It is worth supplementing that the coating thus removed can be reused in the spraying process, with important economic savings. It is also worth observing that the solvent is generally contained in at least a storage and recycling container, in which the clean pure solvent is initially placed and to which the solvent is returned, which gradually becomes increasingly dirty as the spraying proceeds. The cleaning solvent must be replaced or replenished periodically. The storage vessel itself must be routinely cleaned/maintained.
In the art, devices provided with at least a cleaning trolley are known. Such a cart may be accessed from the side of the device or from a different point in the front of the device.
EP3312110a1 and EP3593909a1 of the same applicant describe cleaning carts that can be accessed from the side of the apparatus, i.e. carts that are extracted from a spraying apparatus by translating the cart in a direction perpendicular to the feeding direction of the workpieces to be sprayed.
EP3312110a1 describes two different units, a recovery unit 3 and a cleaning unit 4, which are provided with containers 19 and 19' for cleaning solvent, respectively. The container is part of the unit.
EP3593909a1 describes a cart comprising two subunits, a first subunit for recycling paint and a second subunit for cleaning; the first and second subunits are provided with a container 131 and a container 231 for collecting and recycling the solvent. Each container 131 and 231 is arranged inside the respective subunit.
The main advantages of the side-draw carts and in particular of the carts described in the above mentioned documents are: by means of this extraction, the cleaning trolley can be replaced for maintenance without the production line having to be stopped.
On the other hand, EP1964795a1 of the same applicant describes a front access cart which is drawn out of a painting apparatus by translating the cart in a direction parallel to the feed direction of the workpieces to be painted. The cart is provided with a cleaning system comprising a counter roller in contact with the lower return section of the main conveyor to be cleaned, and with a second stage conveyor for cleaning the counter roller. Typically, the cart is provided with a dual storage and recirculation vessel for cleaning solvent, which is provided with a recirculation pump.
In the known art, and in the vast majority of cleaning carts produced by the applicant, two circuits are provided, in which the solvent is, at each point of its path, two circuits directed totally differently, but which are preferably served by a single peristaltic pump. The first loop is a loop that removes paint, thus providing a relevant amount of recyclable paint in its respective recycling container. The second circuit is a suitable cleaning circuit that directs a solvent containing a smaller amount of dope relative to the first circuit. The fact that the two circuits are completely different allows the use of two different solvents; for example, the first loop directs acetone, while the second loop directs water.
Although not shown in the drawings, it is noted that the spraying equipment is generally part of a production line, comprising equipment performing different operations placed one after the other in series. This also results in difficulty in accessing the cleaning cart from the front and in extracting the cleaning cart from the painting device.
In all the above described prior art carts all the components forming part of the paint recovery unit and/or the cleaning unit are placed on the cart, in particular at least one storage container for recycling the solvent is placed on the cart.
In some types of equipment, once the cart is inserted into the painting equipment, the front cart is no longer accessible to maintenance personnel. Even to replenish the solvent used to clean the belt conveyor, equipment is required to stop to access the front cart.
Due to the obvious negative economic consequences of a stoppage, a production line stoppage is particularly not favoured by the manufacturers who use the painting installations produced by the applicant.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to provide a cleaning cart for paint recovery and cleaning that allows maximum paint recovery and cleaning efficiency, which can be used while minimizing downtime. In particular, the cleaning cart is a front access cart representing the most common type.
This object is achieved by a device having the features of the present invention.
The cleaning trolley according to the utility model is inserted into and withdrawn from the spraying device in a direction parallel to the feed direction of the workpiece to be sprayed; in particular, the cleaning cart is provided with a front access portion.
A solvent storage and recycling container for recovering and recycling solvent is separated from the cleaning cart and placed on the side of the spray equipment. This allows maintenance personnel to access the solvent storage and recirculation vessel to replenish the solvent, or to clean and/or replace the solvent storage and recirculation vessel, without stopping the spraying of the workpiece.
A first advantage of the present invention is that it is possible to prevent the production line from being stopped due to cleaning and maintenance of the cleaning cart. This advantage is particularly interesting in complex production lines comprising a plurality of different machines placed in series, in which the stop of a single machine means the stop of all the other machines that make up the line.
A second advantage is that the painting device provided with the cleaning trolley according to the utility model can be used in three consecutive production shifts of a working day without stopping the production line and thus taking up downtime, with the economic advantage of being easy to imagine.
A third advantage consists in the easy access to the solvent storage and recirculation container according to the utility model with respect to the front cleaning trolleys according to the known art. In fact, when arranging the solvent storage and recycling container on the cleaning cart, maintenance personnel have to lie under the equipment to access the solvent storage and recycling container. Of course, this often makes it difficult and even dangerous for maintenance personnel to maintain the equipment.
Drawings
Further advantages and characteristics of the utility model are disclosed in the following description, wherein exemplary embodiments of the utility model are explained in detail on the basis of the figures:
fig. 1A and 1B are side and isometric views of a detail of a cleaning cart according to known technology;
fig. 2A and 2B are side and isometric views of a detail of the cleaning cart according to the utility model inserted into the spray booth (working position);
fig. 3A and 3B are side and isometric views of a detail of the cleaning cart according to the utility model withdrawn from the spray booth (rest position).
Detailed Description
Fig. 1A and 1B show a detail of a cleaning trolley according to the known art in a side view and in an isometric view, respectively.
The trolley 1 is provided with a front access, i.e. the insertion/extraction of the cleaning trolley into/from the painting apparatus (not shown) by translating the trolley in a direction parallel to the feed direction of the pieces to be painted.
The trolley 1 is provided with at least one storage container, preferably two storage containers 2, which are containers of solvent for cleaning the belt conveyors well known in the art, with the aim of removing the paint residues that soil the belt conveyors, which may soil the pieces to be painted. As explained in the introduction, the first circuit is a paint recovery circuit and the second circuit is a cleaning circuit. The two circuits are different over their entire path, so that two different solvents can be conducted, but a single pump serves both circuits.
The one or two containers 2 for solvent storage and recycling are typically integral with the cart 1; in order to replace/replenish the solvent, the cart must be accessed from the front of the spraying equipment, which requires stopping the production line, i.e. the spraying of the work pieces.
FIGS. 2A, 2B, 3A and 3B illustrate the present invention; shows that: the only supporting frame 25 of the booth, which is the supporting frame of the booth; and a conveyor system for the workpieces to be painted, which is a closed belt conveyor 21 as is well known in the art. In fig. 2A, 2B, 3A and 3B, a thick arrow indicates a feeding direction of a workpiece (not shown) to be painted.
Figures 2A and 2B show details of the cleaning cart 11 in side and isometric views, respectively; in both views, the cleaning trolley is shown in its working position, i.e. in its inserted position below the belt conveyor 21, which conveys the workpiece to be painted (not shown). Typically, the belt conveyor rotates about a motorized roller (not shown) and an idler roller (not shown).
The solvent storage and recirculation container 22 is placed in a position accessible by the side of the spraying apparatus, i.e. from a direction perpendicular to the feeding direction of the workpiece to be sprayed.
In the preferred embodiment, two solvent storage and recirculation vessels 22 are provided.
Figures 3A and 3B show a detail of the cleaning trolley according to the utility model in a side view and an isometric view, respectively; in both views the cleaning trolley is shown in its rest position, i.e. in its position withdrawn from under the belt conveyor 21 which conveys the workpiece (not shown) to be painted.
It can be easily observed by comparing the different figures that the solvent storage and recirculation vessel 22 is separate from the cleaning cart 11. By the detached position of the solvent storage and recirculation container 22 with respect to the cleaning trolley 11 is meant that the position of the solvent storage and recirculation container 22 is not changed by the translation of the cleaning trolley 11 in a translation direction parallel to the feeding direction of the conveyor belt, when the cleaning trolley 11 is inserted/extracted to bring it from its rest position to its working position and from its working position to its rest position.
The solvent storage and recirculation vessel 22 is placed on the side of the spray equipment in a location that is easily accessible to maintenance personnel who must clean the solvent storage and recirculation vessel 22 and/or replenish and/or replace the solvent contained in the solvent storage and recirculation vessel 22.
Removing at least one solvent storage and recirculation vessel 22 from the cleaning cart 11 and placing it on the floor allows the solvent storage and recirculation vessel 22 to assume a theoretical plurality of positions on the floor. The multiple locations may lead to malfunction of the cleaning cart, particularly the fact that solvent flows out of the solvent storage and recirculation vessel 22. Therefore, said at least one solvent storage and recirculation container 22 must adopt and maintain a well-defined position with respect to the cleaning trolley 11, in particular with respect to said supporting frame 25 of the spraying apparatus, when it is in operation.
In an embodiment, said at least one solvent storage and recirculation container is engaged inside a positioning frame 23, which in turn is placed in a preset position, preferably between the recirculation pump 24 and said support frame 25 of the spraying apparatus, to ensure the correct positioning of the solvent storage and recirculation container 22 with respect to the cleaning cart 11.
Different configurations may be provided: in the first configuration, the positioning frame 23 is anchored to the ground and the solvent storage and recirculation vessel 22 is extracted by lifting it. In a second configuration, the positioning frame 23 is mounted on sliding guides and the solvent storage and recirculation vessel 22 is translated laterally to withdraw it from under the spray equipment.
Typically, the solvent storage and recirculation vessel 22 is provided with a partial lid that limits solvent evaporation, while the spray equipment is provided with a suction system that collects solvent fumes.
A first valve (tap) 27 is placed at the end of each return pipe 30, which directs dirty solvent from the cleaning cart 11 back to the solvent storage and recirculation vessel 22. The small thick arrow shows the direction of the solvent.
In normal operation, the two first valves 27 are open and must be closed in order to extract the solvent storage and recirculation vessel 22 for maintenance. The first valve 27 must also be closed when the cleaning trolley 11 is drawn out from its position under the painting equipment.
In a preferred embodiment, each solvent storage and recirculation vessel 22 is provided with its own second valve 28, so as to allow emptying of the solvent storage and recirculation vessel 22 and at least partial replacement of the solvent even during operation of the spraying device. The replenishment and partial replacement of the solvent can be carried out even when the coating apparatus applies the coating material to the workpiece, without stopping the coating apparatus.
It is noted that the return pipe 30 for guiding the dirty solvent is provided with a diameter wider than the diameters of the first delivery pipe 26 and the second delivery pipe 29. In this manner, each return line 30 can be used as an additional vessel when its respective first valve 27 is closed, for example when its respective solvent storage and recirculation vessel 22 is replaced. This adds flexibility to the system.
In practice, the sequence of operations to be performed at the end of a work shift (i.e. when stopping spraying) is:
-stopping the spraying equipment;
-closing said first valve 27;
translating the cleaning trolley in a direction parallel to the feed direction of the pieces to be painted, to withdraw the cleaning trolley 11 from below the painting equipment;
placing a bucket below said first valve 27, which bucket will contain the cleaning solvent remaining in said pipe;
-reopening said first valve 27;
-maintaining the cleaning cart 11;
-withdrawing and cleaning the solvent storage and recirculation vessel 22.
In order to restart painting the workpiece, the same operations listed above must be performed in reverse order, replacing the solvent storage and recirculation vessel 22 and the cleaning cart 11 to their working positions before opening the first valve 27.
Obviously, in the maintenance of the solvent storage and recirculation vessel 22, it is necessary to pour an appropriate amount of cleaning solvent into the solvent storage and recirculation vessel 22 when the spraying equipment is initially set up. As a result of the guiding of the solvent performed by the recirculation pump 24, the solvent is used for cleaning operations inside the cleaning cart 11. The solvent becomes increasingly dirty as the working day progresses during its recycling. Maintenance personnel decide whether and when the solvent must be replenished and/or replaced, preferably using the second valve 28; the maintenance is performed without stopping the spraying equipment.
